Management of shoulder impingement syndrome and rotator cuff tears.

Rotator cuff impingement syndrome and associated rotator cuff tears are commonly encountered shoulder problems. Symptoms include pain, weakness and loss of motion. Causes of impingement include acromioclavicular joint arthritis, calcified coracoacromial ligament, structural abnormalities of the acromion and weakness of the rotator cuff muscles. Conservative treatment (rest, ice packs, nonsteroidal anti-inflammatory drugs and physical therapy) is usually sufficient. Some patients benefit from steroid injection, and a few require surgery.
